In order to ensure that the steering sheet 41 and the turntable 51 rotate around the center, a steering sheet through hole 414 and a turntable through hole 514 are respectively formed in the center of the steering sheet 41 and the center of the turntable 51, and a center shaft column 114 passing through the steering sheet through hole 414 and the turntable through hole 514 is arranged on the fixed seat 33 and/or the water outlet panel 1, so that the steering sheet 41 and the turntable 51 rotate around the center shaft column 114.

The water pressure control device is used for controlling the water pressure of the water inlet pipe, and for the prior art, the switching mode can be rotation, pressing and lifting, and can also be integrated with the existing temperature control valve to be positioned at a position convenient for manual adjustment.

For the present case, two functional water cavities are taken as an example to illustrate the usage principle of the present invention, specifically, each functional water cavity needs two movable sealing blocks 11 symmetric about the center of the water outlet panel for control, and the turntable 51 is provided with two symmetric control blocks 512 corresponding to the movable sealing blocks 11.

In the natural state of the present invention (the water inlet pipe is in a low pressure state), the pressure-bearing device 3 is located at the topmost position under the action of the return spring 33, the guide pillar 312 of the pressure-bearing plate 31 is located at the high position of the inclined guide surface 411, the inclined guide surface 412 of the turning plate 41 is embedded into the chute 511 of the rotary plate 51, the control block 512 of the rotary plate 51 is aligned to the movable sealing block 11 of the first functional water cavity, the first functional water cavity is correspondingly opened or closed, and at this time, the shower head is in the first functional water state;

when the functional water of the shower head needs to be switched, a user controls the water pressure of the water inlet pipe to increase through the water pressure control device, so that the pressure-bearing sheet 31 moves downwards under the action of the water pressure, the guide pillar 312 of the pressure-bearing sheet 31 moving downwards extrudes the inclined surface of the upper inclined guide surface 411, further the steering sheet 41 is pushed to rotate and the torsion spring 42 is rotated to accumulate force, in the process, the lower inclined baffle surface 412 clamps the side surface of the inclined groove 511, so that the steering sheet 41 rotates to drive the turntable 51 to rotate for a certain angle, at this time, the turntable 51 rotates clockwise for a preset angle (such as 60 degrees) from top to bottom, and then the turntable 51 continues to rotate for a preset angle (such as 30 degrees) through the attraction force of the control magnet 513 and the sealing magnet 113 until the turntable 51 rotates to the control block 512 of the turntable 51 to align to the movable sealing block 11 of the second functional water chamber (i.e., the turntable rotates for 90 degrees overall), so that the second functional water chamber is correspondingly opened or closed, and at this time, the shower head is in a second functional water state;

when switching is needed again, a user firstly controls the water pressure of the water inlet pipe to be reduced through the water pressure control device, so that the pressure-bearing piece 31 moves upwards under the action of the return spring 33 to enable the guide post 312 to not press the steering piece 41 any more, at the moment, the rotating disc 51 does not rotate under the action of the control magnet 513 and the sealing magnet 113, and the steering piece 41 rotates under the action of the torsion spring 42 to enable the lower inclined guide surface 412 of the steering piece 41 to be completely separated from one inclined groove 511 on the rotating disc 51 and embedded into the next inclined groove 511; then, the user controls the water pressure of the water inlet pipe to increase through the water pressure control device, the pressure-bearing sheet 31 moves downwards under the action of the water pressure, so that the rotary disc 5 rotates to the control block 512 of the rotary disc 51 and aligns to the movable sealing block 11 of the first functional water cavity, the first functional water cavity is correspondingly opened or closed, and at the moment, the shower head is in the first functional water state.

Further, in order to ensure that the pressure-bearing sheet 31 can be quickly reset when the water pressure of the water inlet pipe is controlled to be reduced by the water pressure control device, the body 2 is covered with a water drainage gland 6, and a gap is formed between the water drainage gland 6 and the body 2; specifically, a raised annular ring 21 is arranged on the water inlet, a through hole corresponding to the water inlet is arranged in the middle of the water discharge gland 6 so as to communicate the water inlet with the water inlet pipe, and a sealing gasket 61 is arranged between the through hole and the annular ring 21; when high-pressure water flows, the water flow applies pressure to the sealing washer 61, so that the sealing washer 61 completely wraps the annular ring 21, the through hole and the water inlet are sealed, and the water flow completely flows into the water inlet and cannot flow out from a gap between the water drainage gland 6 and the body 2; when no water flow exists or the water pressure is insufficient, the pressure borne by the sealing washer 61 is insufficient to enable the sealing washer 61 to completely wrap the annular ring 21, the through hole and the water inlet cannot be completely sealed, and at the moment, the water flow flows out from a gap between the drain gland 6 and the body 2, so that the pressure borne by the pressure-bearing sheet 31 is quickly reduced, and the resetting of the pressure-bearing sheet 31 is accelerated; the annular ring 21 may be formed of a plurality of tooth-like projections to facilitate the flow of water out of the gap between the drain cover 6 and the body 2.

To sum up, the utility model discloses a water pressure controlling means on the inlet tube controls the water pressure change in gondola water faucet water route, and then utilizes water pressure change to drive pressure-bearing device 3 and reciprocate, and diversion drive arrangement 4 then changes reciprocating of pressure-bearing device 3 into the rotation, and then comes the rotation of driving function water auto-change over device 5 to switch the water route of the different function waters of gondola water faucet and switch, reached the effect that utilizes water pressure to realize the water route of the different function waters of gondola water faucet and switch, make the gondola water faucet have advantages such as convenient to use, easy operation.
